PATENT OFFICE IRVING R. IIIPKKPENMEY'EN, or WAUKEGAN, ILLINOIS, AssIGNoRToy THE CREAMERY kPACKAGE MFG. COMPANY, oF CHICAGO, ILLINOIS, ACoRroRATIoN or ILLINoIs p srBAYING DEVICE Application tiled September20, 1926. Serial No. 136,410.

Theinvention relates to spraying devices, more particularly to pressurespraying jets as employed in bottle and can washing machines.

In the washing of milk bottles it is the practice to spray the interiorof the bottles with a cleansing solution under pressure, the spray beingdischarged from movable jets passed into the bottles. Itv is desirablethat the sprayed solution directly strike the surfaces of the bottle atall points to thoroughly re-kr move the soil therefrom. As the spentsolution is returned to the supply reservoir, it often happens that thejet orifices become clogged and lose their eiciency by reason of theaccumulation about the orifices of sediment from the solution.

It is the principal object of this invention to provide an improvedconstruction of spraying jet which yminimizes clogging of the oriiicesby automaticallyclearing them during operation, and the parts of whichare readily disassembled for cleaning. A further object is to provide ajet construction which discharges both a direct stream and continuouscircular sheets of liquid at varied angles.

Other objects and advantages will be apparent in the following detaileddescription of a preferred embodiment of my invention which Ihaveillustrated in the accompanying drawings. It will be understood,however, that various changes in form, construction and arrangement maybe made by those skilled in the art without departing from the scope andspirit of the invention as expressed in the appended claims.

Referring to the drawings Fig. 1 is a sectional elevation of thedevice.y Fig. 2 is a view in elevation of the parts in separatedrelation with a portion shown in section. Fig. 3 is a detailed plan viewof the ring member forming the side orifices, and Fig. lis a crosssectional plan view taken on the planek rinsing solution, and is usuallycarried by y mechanism for passing the spraying devices carried by thetube into and out of the' passing containers. This latter mechanism,being well known in the art, is not herein disclosed. The end portion ofthe tube 1 carries a sleeve 2 ofy dimensions sufficient to provideaspace between the sleeve and the end portion of the tube extendingwithin it. The sleeve 2 is secured at one end to the tube, as at 3, insealed relation thereto, the other end of the sleeve terminating nearand preferably outwardly of the end of the tube. A pair of. ports 4opening through the tube gives communication from the tube into theannular chamber between the tube and the sleeve.

- The end of the tube 1 supports a member 5 preferably threaded into thetube end and forming a closure therefor, and carrying at its outer endan enlarged head 6,' preferably of diameter similar to the outerdimension of the sleeve 2. y The member 5 is provided with an axialpassage 7 in communication with the interior of the tube 1 and extendingthrough the end of the head 6. The inner face'of the head (Sispreferably tapered upwardly and outwardly as indicated at 8, and the endof the sleeve 2 is preferably tapered downwardly and outwardly as at 9.`

i Positioned between the head face 8 and the sleeve end 9, is a ring 10of substantially similar cross dimensions as the sleeve Q. The ring 10is spaced from boththehead and the end of the sleeve, the adjacent'edgesof the ring being' tapered in similar angular form as' the adjacentfaces of the head andsleeve end respectively. The ring 10 is lprovidedon its permit both rotative and longitudinal movement of the ring uponthe member 5.1 The member 5 is provided with a shoulder 12 which ise'l'ective as a stop for the lugs 11, so that when the lugs are inlposition of contact with the shoulder' 12 the ring 10 is positionedapproximately equi-distant from the head face 8 and theend 9 of thesleeve. l

In operation, washing solution is vsupplied to the tube 1 underpressure, and is discharged by the device herein described' Vina directstream from the passage 7, and also in a circular upwardly-directedcontinuous curtain of spray from the oriiice between the ring 10 and thehead face 8 and in a downwardly-directed continuous curtain of sprayfrom the orilice between the ring 10 and the end 9 of the sleeve. t willthus be seen that in passing the device into the interior of a bottle orother container the upper stream strikes the bottom of the bottlewithforce while the circular curtains pass over the inner surface ot thebottle at angles which reach all portions.

As the spray device is withdrawn from the bottle and the supply ofsolution cut oit until the nent bottle is in position, the ring 10 dropsbyv gravity into Contact with the end or" the sleeve 2, thus breakingany accumulations of sediment which mayr have lodged upon any portionor" the two circular orifices during the passage of the solution. Thenthe'solution is again delivered to the spraying device under pressure,the first efi Jfect is to sharply lift the ring until the lugs '-11contact with the shoulder stop l2, with the edectk of loosening whateversediment may be adhering to the ring. rlhe ring also changes itsposition in operation by retation which aids in preventing theaccumulation of sediment on the member 5.

Whenever it is desirable to disassemble the device for thoroughcleaning, the removal ot the member 5 from' the tube l permits theseparation of all parts and gives access to all passages for cleaning. Y

I claim as my invention:

l. A device oi the class described,` comprising a tube, a spaced sleevesealed at one end upon said tube and terminatingr adjacent the end ofsaid tube, the space between said tube and said sleeve havingcommunication with the interior of said tube, a member removably securedat the end of said tube having a head spaced from the end of said sleeveand having a passage therethrough coimnunicating inteinally with; saidtube, and a ring loosely mounted on said member and positioned betweensaid head and said sleeve end, 'said ring beine' adapted to form sprayorices with said head and said sleeve end.

SELA devicel of the class described. comprising a tube, a sleevepositioned about said tube and having onerend in sealed attachmentthereto.A the other end ot said sl eve terminating beyond and adjacentthe end of said tube, said sleeve and said tube forming an endwardlyopen annular space therebetween, said tube having a port- Jforcommunication bet-ween'the interior -ot said tube and said space,amember removably secured at the end of said tube extendingbeyond the.free end of said sleeve and having a head spaced longitudinally from,the end ofl said sleeve, said member having a shoulder formed thereonbeyond the end of said tube and facing toward said sleeve, and a ringoperatively positioned between said head and said sleeve end normally inspaced relation to both said head and said sleeve to form spray oricescommunicating with said annular space, said ring having a plurality oflugs loosely bearing upon said member and supporting said ring formovement longitudinally oisaid member, the movement of said ring beingoutwardly limited to normal oriiice-forming position by abutment of saidlugs with said shoulder.

in witness whereof I have hereunto attached my sienature.
